Background: The high number and clinical heterogeneity of neurological impairments in patients with a post-COVID-19 condition (PCC) poses a challenge for outpatient care.

Objective: Our aim was to evaluate the applicability of the proposed subtypes according to the guidelines "Long/Post-COVID" (30 May 2024) and their phenotyping using clinical and neuropsychological findings from our post-COVID outpatient clinic.

Methods: The evaluation was based on cross-sectional neurological and psychological test examinations of the patients, which were carried out using standardized questionnaires and test batteries. In addition, a detailed anamnesis of the current symptoms and a retrospective survey of the acute symptoms up to 4 weeks after the confirmed infection was conducted. The subtypes were classified according to the abovementioned guidelines based on the medical history and selected patient questionnaires, to which we added a 5th subtype with reference to the previous guidelines "Long/Post-COVID" (as of 5 March 2023).

Results: A total of 157 patients were included between August 2020 and March 2022. The presentation was at a median of 9.4 months (interquartile range, IQR = 5.3) after infection, with a mean age of 49.9 years (IQR = 17.2) and more women (68%) presenting, with a total hospitalization rate of 26%. Subtype 1 (postintensive care syndrome) showed the highest proportion of men, highest body mass index (BMI) scores and the highest rates of subjective complaints of word-finding difficulties (70%). Subtype 2 (secondary diseases) was dominated by cognitive impairment and had the highest depression scores. Subtype 3 (fatigue and exercise-induced insufficiency) was the most common, had the most symptoms and most severe subjective fatigue and the largest proportion of women. Subtype 4 (exacerbation) mainly showed affective symptoms. Subtype 5 (complaints without relevance to everyday life) had the lowest scores for depression, fatigue and BMI. Neurological and psychological conditions were frequently pre-existing in all groups.

Discussion: The management of PCC can be improved at various levels. A standardized subtype classification enables early individually tailored treatment concepts. Patients at risk should be identified at the primary care level and informed about risk factors and prevention strategies. Regular monitoring of cardiovascular risk factors and physical activity are essential for PCC treatment. In the case of cognitive deficits and concurrent affective symptoms, psychotherapeutic support and drug treatment with selective serotonin reuptake inhibitors (SSRI) should be provided at an early stage.

Mental healthcare in South Tyrol, as everywhere in Italy, is still characterized by Law 180, which came into force in 1978 under the leadership of Franco Basaglia and Bruno Orsini. The Ministry of Health subsequently set a target number of beds of 10/100,000 inhabitants. Unlike in other parts of Italy, private clinics play a minimal role in South Tyrol. The "Psychiatric Services" are part of the state healthcare system responsible for all citizens and are also responsible for compulsory outpatient care. According to the concept of community care, also due to the small number of inpatient beds, a great deal of care is provided on an outpatient basis. Coercive measures can only be used in the case of an illness requiring urgent treatment that the patient refuses, without recourse to endangering circumstances (self-endangerment or danger to a third party). Inpatient hospitalization is only possible if treatment also takes place and the principle of "outpatient before inpatient" also applies in this context, i.e., coercive treatment can only take place as an inpatient if it cannot be carried out as an outpatient. Forensic psychiatry has very few places and mentally ill offenders are often in prison or occupy beds in general psychiatric wards. Compared to Germany there are fewer beds available but staffing levels are better, particularly for nursing. In relation to the number of inhabitants, compulsory treatment is more frequent than in Germany, whereas involuntary hospitalization and physical restraint are much rarer (only possible in Italy by court order).

Inflammatory causes of stroke are frequent and often pose diagnostic and therapeutic challenges due to the scarcity of randomized trials and the absence of clear guideline recommendations for many scenarios. Following the publication of the recommendations of the European Stroke Organization on primary angiitis of the central nervous system (PACNS) last year, the German Neurological Society (DGN) has issued very clear guidelines this year on the diagnostics and treatment of PACNS and updated the recommendations for systemic vasculitides; however, stroke often occurs not only as a result of primary vascular inflammation but also as a complication of another organ infection. Approximately 5% of all patients with sepsis, ca. 20% of patients with bacterial meningitis and up to 40% of patients with bacterial endocarditis suffer from a stroke as a complication. This article summarizes the key characteristics of these inflammatory causes of stroke and particularly focuses on the current recommendations for diagnostic and therapeutic management.

Objective: While the neuronal mechanisms of epileptic hyperexcitability (HE) have been studied in detail, recent findings suggest that extraneuronal, mainly immune-mediated inflammatory and vascular mechanisms play an important role in the development and progression of HE in epilepsy and the cognitive and behavioral comorbidities.

Material and methods: Narrative review.

Results: As in autoimmune (limbic) encephalitis (ALE/AIE) or Rasmussen's encephalitis (RE), the primary adaptive and innate immune responses and associated changes in the blood-brain barrier (BBB) and neurovascular unit (NVU) can cause acute cortical hyperexcitability (HE) and the development of hippocampal sclerosis (HS) and other structural cortical lesions with chronic HE. Cortical HE, which is associated with malformation of cortical development (MCD) and low-grade epilepsy-associated tumors (LEAT), for example, can be accompanied by secondary adaptive and innate immune responses and alterations in the BBB and NVU, potentially modulating the ictogenicity and epileptogenicity. These associations illustrate the influence of adaptive and innate immune mechanisms and associated changes in the BBB and NVU on cortical excitability and vice versa, suggesting a dynamic and complex interplay of these factors in the development and progression of epilepsy in general.

Discussion: The described concept of a neuro-immune-vascular interaction in focal epilepsy opens up new possibilities for the pathogenetic understanding and thus also for the selective therapeutic intervention.

Objective: Which theoretical and practical competences do the neurological and psychiatric case histories of the Hippocratic Corpus convey?

Material and methods: The 431 Hippocratic case histories have been studied for reports and communication on the diagnostics, treatment and prognosis of single persons and groups of patients suffering from neurological and psychiatric diseases.

Results: In the 7 books of the Hippocratic Epidemics, a total of 128 patients with neurological and psychiatric symptoms are described. Epidemic fever and its variants were the leading predisposing conditions and the main symptoms were delirium, coma, insomnia, headache, speech disorders and convulsions. A number of patients with phrenitis and opisthotonos are also reported. The majority of the sick persons were male, were teenagers or adults and 47 of them are mentioned by name. The patient's information about the course is often just as informative as the doctor's observations. Treatment was limited to physical and dietary measures.

Discussion: The Hippocratic physician diagnosed and attempted to treat a large number of neurological and psychiatric diseases. The often almost continuous observations of the patients led to astonishingly precise predictions of the course and the prospects of recovery. Numerous symptoms described in the case studies, including carphologia and opisthotonus, have entered the neurological vocabulary. The retrospective etiological analysis of the reports leads to the almost explicit identification of neurosyphilis and encephalitis lethargica. The therapeutic measures described by the author were, as the changeable course of the diseases shows, only of limited effectiveness despite a very differentiated application over time, both against the underlying diseases and the neurological and psychiatric complications.
